Server chronicles - testing fan proposal

The HP ProLiant DL360p Gen8 has 8 fans to cool down the two CPUs and other hardware.

These fans are high speed PWM controlled fan and are prone to fail over time.

The only thing to do is to replace the defective fan with a new one, but it would be nice to understand exactly what the problem is and check if the replacement fan is working before to open the server.

Repairing an electric curtain

Once again, I did find in a flea market for few $$ something that interested me : an electric curtain.

It was still sealed (apparently) and everything supposed to be in it, it was.

But of course ... it was .. it is, broken.

Let see if it can be fixed. If not ... well, is a very good source of interesting components !

My Meshstastic

I'm always curious and so time ago I found out about Meshstastic browsing around.
For a while I said "meh, OK, cool, no time, no resources, no ...." yeah.

Then I did try for a while a kind of equivalent service based only on smartphone : Bitchat 

I like the idea of both, but of course finding somebody on Bitchat is like to win a lottery ticket .. so everything went back on the back back back burner.

Then one day I decided to try to do something with Meshstastic and here we are 

Fitbit Wellness Report

One of the reason to pay for Fitbit Premium was the possibility to generate a 30 days Wellness Report.

I did use that every time before to go to a doctor, it is a nice way to report some physical data.
Since last year, Fitbit (or better Google who did buy Fitbit) decided to remove the possibility to have the Wellness Report.

Why ? Who knows.

EcoFlow Delta-2 MAX - reading device via API

The EcoFlow Delta-2 MAX has an Android application that can monitor and handle the generator.

It can show the battery charge and the instant load/discharge, enable/disable outputs, etc.

Hover one thing is missing : create and show a graph reporting the loading/discharge of the battery, to see for example how much the solar panel contribute to the charge and similar info.

3D Printing - Octoprint renewal - part 1

Basically since the beginning I did use Octoprint to control my glorious Ender 3.

OctoPrint has to run somewhere, so I did use a Raspberry Pi 3B to run it but all things age and I did reach the moment to update it.

Eton American Red Cross SOLARLINK Portable Radio ARC FR600

On an antique mall I did find this nice radio, little bit dirty but otherwise in good shape.

Some cleaning notes.

Emergency power system - logistic

Sometime the power can goes off in the area.

I decided to buy an EF ECOFLOW Solar Generator DELTA 2 Max 2048Wh with 400 W solar panel to charge the Solar generator for long outages.
